Boulware, 23, wound up signing a three-year, $1.66 million contract with the Panthers as an undrafted free agent out of Clemson back in May. He was set to make base salaries of $465,000 and $555,000 over the first two years of the contract when the Panthers cut him loose as they cut their roster down the 53 players.

The 49ers signed him to a contract last week.

During his college career at Clemson, Boulware recorded 261 tackles, 26.5 tackles for a loss, eight sacks, five interceptions with one being returned for a touchdown, seven forced fumbles, and four pass defenses.
